SPECIFICATION forming part of Letters Patent No. 406,300, dated July 2, 1889.

Application illedNovember 30, 1888. Serial No. 292,260. (No model.)

To all whom it may concern:

Be it known that we, JOHN Il. PENDLETON, of Brooklyn, inthe State of New York, and

ANDREW BRYSON, Jr., and CORNELIUS TIERS,

of the city and State of New York, have invented an Improvement in Cable-Grips, of which the following is a specification.

This invention is especially available with traveling cables that are within a conduitor case buried in the earth.

The object of this invention is to pick up or to drop the cable, as required, to start the endless belt of grip-blocks in motion before the grip itself is brought into action to grip the cable between the endless belt'of blocks, and a shoe to cause the movement of the cable to be communicated to the car, also to support the gripping apparatus as the car moves around the curve, and lastly to drop the entire gripping apparatus away from the car should there be any injury to the cable causing the same to become entangled in the grip, so that the car may be stopped in case of an emergency.

In the drawings, Figure 1 is a cross-section illustrating the improvements as applied to the platform of the car. Fig. 2 is an elevation, partially in section, at the line oc ,'Fig. l. Fig. 3 is a plan view of the parts below the platform of the car. Fig. 4 is a sectional plan View in larger size at the line y y, Fig. 2, and Fig. 5 isa partial sectional elevation at the line .e c, Fig. 2. Fig. 6 is a section of the latch for holding the chock-lever.

The platform A, wheels B, and axles B are of ordinary character, and upon the axles B are bearings C, supporting the longitudinal bars or frames C', and there are crossframes C2, the parts being' constructed so as to receive the moving 'parts of the apparatus, hereinafter described.

Upon the frames C are bearings 2, for the longitudinal shafts D, upon which are hooks 3, that support the plate F, which plate supports and carries the gripping device,herein after described, so that when these hooks 3 are separated the plate F can be dropped, tog'ether with all the parts of the grip, in order that the car may be stopped, While the gripping device may be carried along with the ever, shown the lever-arms 4 as extending above'the shafts D and connected by links 5 to the three-armed lever G upon the fulcrum 6, the third arm of which lever is connected by a link 7 to an arm S upon the longitudinal shaft 9, that is beneath the platform A and acted upon by a lever G Whenever itbecomes necessary to drop the plate F and the parts therewith connected, there being a lever G at each end of the car.

Beneath the plate F is a hanging standard H, that passes down into the trunk or conduit K, in which is the cable L, and this hanging standard is sufiiciently thin to pass through the slot in the top of the trunk or conduit, and this trunk or conduit is to be of any desired character and of a size to receive the parts of the grip hereinafter described.

Upon the lower portion of the hanging standard'II is bolted or cast the block I-I, having a recess for the reception ofthe horizontal wheel M upon a vertical axis,`and this wheel M projects at each side farther than the surface of the block H', and within the I trunk Or conduit -K,wherever curves may occur, the guard-rail N is afiixed, as represented in Fig. l, against which this wheel M rolls to prevent the parts being injured by a lateral strain of the cable as the car travels around the curve, and this stationary guard-rail N may be at either side of the horizontal wheel M, according to the-direction of the curve in the track and in the trunk'or conduit.

The block II is formed with jaws, Yas seen in Fig. 4, for the reception of the wheels O 0', around which passes the endless belt P, having grip-blocks lO upon the surface thereof, which grip-blocks are preferably recessed to fit over the cable L. This endless belt and the grip-blocks may be constructed in any desired manner. IVe have represented the grip-blocks as composed of layers or sections fastened to belts of leather that pass around the wheels O O. At each side of the endless roo belt and grip-blocks are the guard-plates 12, bolted upon the opposite surfaces of the block ll. It will now be understood that the endless belt of gri p-bloeks and the hanging standard Il always remain in a fixed position in relation tothe plate F; but at each side of the hanging standard ll are the slideways for the reception of the vertical slides Q. These vertical slides Q are connected at the top by the cross-piece or frame 13 and at the bot-tom by the longitudinal bar Q, the ends of which bar Q' extend to and receive the gudgeons or shafts 14 of the pick-up wheels R. These wheels R are conoidal, the peripheries being concaved and the wheels occupying an inw clined position, as shown in Fig. 1, in order that the cable may rest in the concave upper surfaces of these wheels R, and these wheels revolving freely prevent friction upon the cable when the car is at rest.

Upon the slides Q is the grip-shoe S, the upper surface of which is grooved longitudinally for the cable, and the ends of the grooves are made flaring or beveled, so that there are not any sharp angles with which the cable can come into contact, and toward the ends of the grip-shoe S are the hooks 15, that rise above the upper surface of the shoe, these hooks, also, are rounding at the edges, so that there are no angles to come into contact with the cable.

It is now to be understood that after the cable has been picked up, as hereinafter described, and it travels upon the wheels R and above but not in contact with the surface of the grip-shoe S, the cable will not be exposed to wear or friction; but when the slides Q are raised su ficiently to bring the top surface of the cable L in contact with the grip-blocks 1() on the endless cable P, as illustrated in Fig. 2, the endless belt will revolve by contact of the grip-blocks with the cable, but the car will still remain quiescent, and as the slides Q, shoe, and wheels are still further raised the cable will be bent downwardly and the grip-shoe brought into contact with the under side of the cable and friction applied thereto, until finally the cable is clamped between the grip-shoe and the endless belt and the motion given to the car corresponds tothe speed of the cable.

In order to raise and lower the vertical slides Q and the parts carried by the same, any suitable mechanism may be employed; but we prefer` to make use of a toggle movement, the same being composed of a crankarm 23, upon a gudgeon or short shaft 22, that projects from the block 18, that is received between the lugs 19 on the cross-piece 13of the slides Q, and by making' use of a key or wedge 20, passing through the block 1S and lugs 19, the gudgeon 22 may be raised or lowered to adjust the part-s and compensate any wear. There is upon the plate F a bearing 21. for a short shaft 17, at one end of which is a crank-arm 1t, united by a pin 2l to the so as to forni therewith a togcrank-arm to,

glo-joint, and at the other end of the shaft 17 is a gear-wheel 2o, the teeth of which mesh into teeth upon the rack-bar T, which bar T passes through and is supported by the crossframe C, and at the ends thereof are rods 27, that pass to chains and vertical shafts with lhand-wheels, hereinafter described, so that by turning these vertical shafts and handwheels the rack-bar T can be moved in either one direction or the other, and when moved in one direction the cranks 23 and 1G, acting as toggles, force up the cross-piece 123, vertical slides Q, raising the bar Q', grip-shoe S, and wheels R to lift the cable, and finally clamp the same, as before mentioned, and when the rack-bar T is moved in the other direction the toggle-cranks 1G and 23 move the slides Q downwardly to the desired extent to relieve the grip, dropping the cable or picking up the cable, as hereinafter explained; and we remark that the plate is recessed, as shown in. Fig. 5, so as to allow for the movement of the crank-arm 1G down to the lowest position.

fithin the trunk K are the wheels U, that support the cable L, these wheels U are conical and flanged at 2S, so that the cable L in its normal position travels at the junction of the conical surfaces of the wheels and of the flange, as shown, by dotted lines in Fig. 1. These wheels U are each supported in a frame 30, with suitable journal-boxes for the shaft of the wheel, and there are diagonal links 3l 32, pivoted at their upper ends to the frame SO, and at their lower ends they are hinged to the blocks Each of these frames 3() has two pairs of diagonal links, and one link in each pair has a footpiece 34, that rests upon a block 85 or stop at the bottom of the trunk or conduit, so that in their normal positions the pair of links 31 32 occupy the diagonal positions shown in Fig. 1; but should the diagonal surfaces of either of the wheels R come into contact with either of the cable supporting wheels U, such wheel U will be moved toward one side of the trunk or eonduit K, the links 31 32 swinging and the frame SOmoving .laterally along with the wheel, and as soon as the disturbing influence ceases to act upon such wheel U the same drops back into its normal position. It is usually intended to pick up the cable between one wheel U and the next; but should an effort be made to pick up the cable adjacent to one of the wheels U such wheel will be displaced later ally by the inclined surface of one of the wheels R or of the shoe S.

Then the vertical slide Q and the parts carried by the same are forced downwardly, so that the inclined faces of the wheels R come into contact with the traveling cable L, such cable L is displaced laterally and slides up the inclined surfaces of the wheels R, near which the cable maybe picked up; and we find practically that it is not necessary to lower the wheels R to the position shown in dotted lines in Fig. l, because as soon as the TOO gudgeons 14 of the wheelsR pass below the cable the traction of the cable is upon the Athe shoe S. Forthis reason the cable can be picked up with facility, and the tension of the cable and movement cause it to pass easily into this position in the shoe. It will, however, be understood that if only the devices heretofore described were made use of the cable could not be dropped, because after the slides Q and parts connected therewith have been lowered the cable would not be discharged from the shoe S, but would remain therein. In order to discharge the cable from the shoe, we make use of the swinging chocks V, pivoted at 37 upon the end portions of the slides Q, where they extend beyond the shoe S, and the lower ends of these swinging chocks are adjacent tothe cable as it lies in the shoe S. The pivots 37 also form pivots for the levers 38, that extend out over the cable, and upon the guard-plates 12 are stationary arms 39 and 40, and through each swinging chock V a bolt 41 passes, the outer end of which is attached to the spring 42, and there is awedge-shaped claw-arm 44 projecting downwardly and backwardly from each lever 38, the Wedge-shaped end of which passes in between the spring 42 and the surface of the chock, so that when the lever 38 is moved downwardlyT the wedge upon the end of the claw-arm acts against the spring 42 to withdraw the bolt 41, and when the lever 3S is moved upwardly the reverse action takes place; and by reference to Fig. 1 it will be seen that the lever 38 has a projection 45 upon it that comes into contact with the proj ection 4G upon the chock V, so that when the slides Q are moved downwardly the levers 3S come into contact with the stationary arms 40, and the further movement causes the projections 45 to take against the project-ions 46, and thel still further downward movement causes the chocks V to be swung by the levers 3S, and the lower ends of said chocks V act against the cable L and throw the same over the hooks 15 and out from the shoe S; and when this takes place the wed ge-shaped clawarms 44 are away from the bolts 41, and the spring 42 is now free to project such bolts into holes in the vertical slides Q, so that such chocks V are held by the bolts in the inclined positions represented by the dotted lines in Fig. 1, and hence the cable is forced away by these chocks Vand cannot be picked up by the wheels R upon the upward movement of the slides Q; but during this upward movement, when the parts approach the position shown in Figs. 1 and 2, the levers 38 come into contact with the stationary arms 39, so that such levers 3S are swung until the wedgeshaped claws 44 pass in under the spring 42 and withdraw the bolts, and the further upward movements of the parts swing the chocks V back to their normal positions, so

that the cable can be picked up by lowering the slides Q and the parts connected therewith until the cable is pressed aside by the inclined surface of the wheels R and shoe S and jumps up into the shoe, as before described.

Upon the frame C CS we place inclines C4, which are in the form of plates, and these run Jover the upper ends of the vertical slides Q after the hooks 3 may have been moved and the plate F dropped, thereby forcing down the vertical slides Q and the parts connected with them, so that they will not come into contact with the axles B or the fenders or lifeguards upon the car.
